Intraparotid facial nerve schwannoma (IFNS) is rarely observed in children compared with adults. Only a few cases have been reported in the literature. After radiological imaging and fine needle aspiration biopsy, an IFNS diagnosis may be skipped and confused with pleomorphic adenoma, which has a high prevalence among patients who have a mass in the parotid gland. The probability of IFNS can be recognized by a close relation between the mass and the facial nerve during the application of parotidectomy and by the frozen biopsy of the mass. The surgeon evaluates the mass and faces with surgical mass excison and facial nerve reconstruction according to the relation between the mass and the facial nerve because there is no diagnostic method for the presurgery diagnosis of IFNS. Therefore, the surgeon should be prepared for the possibility of functional lossin the facial nerve during parotidectomy. This article presents the case of a 9-year-old patient with an IFNS diagnosis who had a surgical operation in our clinic, and the algorithm designed according to the literature for the diagnosis and surgical classification of IFNS, as well as the approaches to facial nerve reconstruction.
